STOOL.

Specification of Letters Patent.

Application filed April 20, 1911. Serial No. 622,316.

To all whom it may concern:

Be it known that we,(1) SAMUEL RYAVE, and (2) HERMAN OBERNAUER, citizens of the United States of America, residing at (1) McKees Rocks and (2) Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Stools, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to stools, and the primary object of our invention is to provide a stool that can be folded into a comparatively small parcel easily carried in a pocket or in a valise.

Another object of our invention is to provide a foldable structure that can be advantageously used by campers, tourists and others asa stool, table or other support.

A further object of our invention is to furnish a stool of the above type with a revoluble seat, the stool being constructed to provide a rigid and durable structure capable of withstanding considerable weight.

With the above and other objects in view the invention resides in a novel construction, combination and arrangement of parts to be hereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein like numerals of reference designate corresponding parts throughout the several views, in which Figure 1 is a side elevation of the stool. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a top plan of the stool folded. Fig. 4 is a side elevation of the same upon a reduced scale, and Fig. 5 is a bottom plan of the folded stool.

A stool in accordance with our invention is made of strong and durable structural steel, and comprises a tubular post 1 having the lower end thereof closed by the shank 2 of a head 3, said shank being welded or otherwise connected to the lower end of the post. The head 3 is provided with radially disposed equally spaced bifurcated arms 4, the bifurcation of each arm providing slots 5 and sets of lugs 6. The lugs 6 are enlarged and apertured to receive bolts 7 retained in engagement with said lugs by nuts 8. Pivotally mounted upon the bolts 7 in the slots 5 are the upper web ends 9 of legs 10, said legs being made of T-bars with the lateral flanges 11 thereof bent, as at 12 to form feet upon the legs 10. The legs 10 can be easilyswung into parallelism with the post 1 and are maintained in a set up position at an angle to the post 1 by a knurled collar 13 slidably mounted upon the post 1. The collar 13 is adapted to fit between the web ends 9 and the post 1 to prevent accidental collapse of the legs 10 when the stool is sustaining a weight.

The upper end of the tubular post 1 is provided with a plurality of bayonet-shaped slots 14 into which engage lugs 15 carried by a flanged sleeve 16 which constitutes a socket. The sleeve 16 fits in the upper end of the tubular post 1 with the flange thereof seated upon the top edge of said post. The flanged end of the sleeve 16 is formed with an annular ball race for anti-friction balls 18 and rotatably mounted upon the balls 18 is a head 20. Depending from the head 20 is a shank 19 which extends through the sleeve 16 and into the post 1. The head 20 is similar to the head 3 and pivotally supported by said head are a plurality of arms 23 adapted to fold into parallelism with the post 1, the head 20 being positioned whereby the arms 23 will swing between the legs 10. The arms 23 are preferably made of T-bars and the upper ends of said arms are provided with buttons 24 adapted to engage in eyes 25 carried by the under side of a connecting member or a seat 26. The seat 26 is preferably made of flexible material, as leather or durable canvas and is preferably rectangular in plan, whereby it can be stretched between the upper ends of the arms 23.

To prevent accidental collapse or folding of the arms 23, a lmurled collar 27 is slidably mounted upon the post 1 and this collar is shifted onto the shank 9 under the lower web ends of the arms 23 when said arms are to be supported at an angle to the post 1. A downward movement of the collar 27 is limited by a projection 28, carried by the outer side of the post 1.

From the foregoing it will be observed that we have devised a stool, table or other support that can be reduced in its longitudinal dimension without sacrificing requisite strength and durability. The structure i1: its entirety can be made of a non-corrosive material finished to present a neat and attractive appearance and the fact that the seat can be revolved adds to the merit of the Patented Nov. 21, 1911.

structure and the comfort of a person using the same.

While in the drawing there is illustrated a preferred embodiment of the invention, it is to be understood that the structural elements thereof are susceptible to such varia tions as fall within the scope of the appended claim.

What we claim is In combination, a hollow post provided at its upper end with a plurality of bayonetshaped slots, a flanged sleeve seated upon and extending in the upper end of the post and provided with lugs engaging in said slots, said sleeve constituting a socket, a head provided with a depending shank, said shank extending through said socket and into the post, bearing balls interposed between the head and the flanged sleeve, a

head secured to the lower end of the post, each of said heads provided with a series of radially-disposed equally spaced bifurcated arms 41:, supporting members pivotally connected to the arms of said upper head, supporting lugs pivotally connected to the arms of the lower head, and means slidably mounted upon said post and adapted to be shifted to engage the pivoted ends of said members for maintaining them at an angle with respect to the post.

In testimony whereof we afiix our signatures in the presence of two witnesses.
